I'm more and more leaning towards the RX-100 for my next underwater rig. Just sold of my E-PL2 and was looking at the OM-D but the RX-100 with the Nauticam housing and a couple of wet lenses seems capable of the same IQ in a much smaller and much cheaper package.

Do provide a report once you've received your housing and used it a bit!

You should get the Nauticam Flip Diopter 25101 ( it is 67mm ), it is very flexible, instead of threading permanently on your Nauticam RX100 67mm thread on its port any wet lens.
